    Here is the video that was embedded into the newsletter.

    The wider extractor was designed because of the reports concerning ripped off rims of steel cased ammunition. The upgrades were implemented based on user feedback and in collaboration with InRange TV.

    The upgraded gas valve now has markings of the three main settings as well as other positions eliminating any confusion. It is a drop-in part and simply replaces the old pattern valve. Below you can find a video telling about the new gas valve.
